TYPE-WRITENG MACZIHNE.

To all whom it may concern:

Be it known that I, CARL 1 LUNDEBERG, a citizen of the United States,residing in Hart: ford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification. y

This invention relates to typewrit-ing niachines in which, in additionto the usual line-spacing mechanism for the revoluble platen, there isprovided an auxiliary mechanism usually at one end of the platen, forfeeding a paper ribbon around the" laten E independently of the latter,or. whi e the platen is stationary. Such strips are employed for thepurpose of recording the amounts of successive bills as the latter are-w-ritt-en upon the main portion of the platen.

The. objects of myinvent'ion are to provide. xiIgQgQIOVG-(Ll means fordetachably mounting t.

spool or spool-holder for the paper ribbof improved means for unwindingthe strip from the spool and for pulling the strip from the stationaryplaten around which it is wrap1. ed, to facilitate the adjustment andmanipulationof the paperstrip, to provide against premature unwinding ofthe paper ribbon from the spool during the operation of the machine, toenable the strip carrying portion of the platen to be moved into theprinting field when desired without linespacing the strip, to providemeans-for regulating the throw of the pawl which feeds the paper ribbonline by line, and to constrr the ribbon feeding a pliance's, so thatitlIlLj readily attache to and c l et a clied from the paper carriagesor platen frames of existin t p'e writin machines.

Atthis figure, the SPOOl-lJIz1liG is shown cast off, and theline feeding parl as silenced. Fig. 5 is a rear perspective v1 of theparts seen 2 i v k and 7 illustrate the construction of a deter: 1. ablespool-holder for the paper ribbon. ,Fig. 8 is a plan showing the usualrevoluble platen and its line feeding meelmnisni as Well as theauxiliary ribbon feeding nice-1mm ism.- Fig. 9.,is a rear perspectivevie-s l. par of the framework of the machine, and. mea whereby there isadjustably mounted there- '.-n a cam for effecting the ,line teeding ofthe paper r1bbon..

My improvements are illustrated in con v nection with the well lznownUnd typewriting machine, in which. i'V strike against the front side ofplaten 2, which is revoliubly mounted-by means of an axle 3 in plateniranewhicl'i.eonipriscpieces 4 and; connecting roar papee.

which drawn along in letter feedini tion by means. of strap 7 and em 8.Said. platen is provided with line sp'aeing mecl'ianisin includin wheel9, pawl 10-, slide 11 and lev J well known ccmstiruction in said *1 andpre re rolls is guide the .n sheets or bills around the platen injrmanner, id. rolls eo op'erating w from, the dowel pen I forwardly be] .epl carriage runs along theusual which-is'indica'ted 'a 5.. I The tallystrip is coiled at 1' P which ishung just" in rearo' the" id i on papershelf 5, so that the strip may be led: l'orwardly from the spool inbetween a feeding roi. 18, and a roll 19 bearing up against the underside thereof and (so-operating therewith to pull the paper or unwind thepaper from the spool. From the. bite of the e rolls, said strip is ledforwardly and (.lownwardly to the platen and around. the under sidethereof, and up in front, so that it may be struck by the types From theplaten, it is carried upwardly and backwardly and passed between thefeeding roll 18 and a roll 20, which presses down to co-operate withsaid feeding roll to pull the printed portion" of the ribbon from theplaten while the lat ter is stationary. It will be understood thatduring the usual revolutions of the platen occurring while writing abill or other doeument, the rolls 18, 19 and 2-0 remain stationary, asWell as the strip of paper 16 and that thenioveinents of the strip aremade while the platen is stationary.

-.The rolls lS may be turnedby means of a finger piece 2L to run thestrip oii' from the spool and simultaneously pull the leading end of thestrip back from. the platen at the same speed. v i v The strip isthreaded line by line. by means. of a ratchet wheel 22 fixed upon theroll 18, and a pawl 23 pivoted at 24 upon an upstanding arm 25 oil aslide 26 which is mounted to move forwardly and backwardly upon screws27 the slide having slots 28 to engage; the screws, and the latter being"threaded into a plate 29 which cooperates with a cinnpai'iion plate 30to support the spool and rolls, To said slide 26 is connected. the freeend. of a. lever 31 detachably pivoted upon a bracket 32 by means of ascrew 33, said bracket fixed to a 'pertoi" the plate 30. From the freeend otgsaid lever depends a pin 34 to engage a cam 35 fixed upon theframework of the machine, so that when the carriage is moved farenougl'i to the leftto bring the strip 16 to the printing point, the pin34 engages the cam 35 and rides thereover, thus vibrating the lever 31.forwardly together with the slide 2-6 and. the pawl 23, to advance thestrip feeding roll 1 8 and the strip thereon.

The top pressure roll 20 is mounted by. means of an axle 36 in the arms37 of a bail i which is hinged at 38 upon said side plates 29 and 30 andis pulled down by a spring 39 to press the roll against the feeding roll18.

The bail may be lifted to release the roll. 20,. since the ends of theaxle 36 extend. through closed slots 40 formed inthe side plates, the

latter being confined between saidbail arms.

abiy of soft rubber, and the roii is preferllhe pressure. rolls l9 and20 are preferably of hard metal provided with'fine longitudinal flutesormilling, as indicatedat F ig. 5, whereby perfect control iand accuratefeeding of the strip isassured. The lower pres sure roll 19jis mounted.likethe 1'0ll'20 lie-- rings to begin a new line. tachably mountml upona spindle or axle 53 tween arms ll of a bail similar to the bail 37, and('onnccledto the lower end of the spring 39; the bail 4-1 being; hingedat 4-2 upon the side plates 2i), 30, and {linux10 -13 ol the roll .19passing through closed slots 44 in said plates. Thus either roll ll) or20 may be released while the other remains in engagement with the mainhieding roll 13, and hence the strip may be tautencd either by willingback the leading end when only the roll 20 is released, or bypullinglnirk the under port ion of the strip when only the roll ll) isreleased, The rolls may also be releasedv simultuneously if desired; andfor convenience in releasing them, the bails may be provided withhandles 45, 46.

Overtlirow or undue unwinding oi the coil from the spool 17 isavoided-11y the use ol ii bra-he in the form of a bail 47 hinged at inupon the side plates 29, S0. A draw-spring 49 is connected at one end toa pin. 50 upon said bail, and at its other end to a pin 5l whereby tohold the bail lightly against the coil of paper ribbon on the spool. Thepin. 51

'is secured upon a shortarm 52 formed upon the pawl 23 and serves tohold the latter in engagement with the ratchet wheel. bail -17 may be.swung up so far that the spring 49 acts upon the other side of bailhinge 48, thereby holding the bail away from the spool, for conveniencein tightening the coils on the spool or inserting or removing the SPOCH,or otherwise manipulatiiu, the same. The lower pressure roll 19 maybesinuiltaneously cast oil, as at Fig. 4, while tlie top roll 20 remainsiii-use so that by turning the spool 17, the entire paper strip may bedrawn taut. l t will also be u'i'ulerst-oo .l, that the strip may be, atthis time, adjusted relatively to the printing line, that is to say thelast line oi writingupon the strip may be drawn down to the usual platenscale simply turning the spool 17,, while the parts are in the Fig. sl

position; and to facilitate the adjustment of the strip the top roll 20may, also be released at this time. This. renders it very convenient tocorrect errors on the paper ribbon. It will also be notibed at Fig. 4,that the sprihg 49 has beencaused to swingthe pawl 23 out 01'' positionto engage the ratchet Wheel 22;so that the latter is not rotated by thepawl iluringthe actuation oi the latter by the slide 26 and leve 31 whenthe carriage is run over to the left to bring the paper ribbon 16 intoposition to be written upon. 4

The spring 39 also serves to draw the slide 26 .rearwardly during thereturn of the car- The spool 17 is deiiavin'g one end. button and at theother end a tumbler 55 pivot-ed at 56 upon theend of the axle and havinga point 57 to facilitate introduction and passage of 'the' axle through,the. side plates and the spool. The tumbler when extended is shown infull The its

lines at Figs. fi-and 7, where it forms a continuation of the axle,having the same q linder contour; but when. the spool rotates, thetumbler gravitates to the dotted line position 6 ,so that one end 58thereof projects,

at .onone side of the axle 53 while the body of the tumbler projects onthe other side ofsaid axle, thereby looking the axle against falling[out of the machine;

"n'ietal plate projecting. forwardly from a bar '1 59 which eaten dsalong the carriage and is de .tachably supported upon the, framework ofh the machine, One end of said bar, 9, is ''coirniected by a screw 60 toan upstanding arm 61. detaoliably secured by a screw 62 ona vpart 63 ofthe framework of the machine, ,ihe other end of-the bar is attached by ascrew 64 to an upstanding arm 65,'which is mounted by a hub 56 upon apivot orgudgoon 67 lia-ring a bearing in the opposite por tion of theframework, whereby this end of the bar 59 may be swnn'gfrom the dottedline to the full line position to permit adj ustrnent v of the camrelatively to the lever pin 34 to regulate the throw of the pawl23. Ascrew 69 is threaded into a part of the arm to strike against theframework 68 to limitthe forward adjustment of the cam 35; and a screw70 is threaded. through the arm 65'below the pivot 6? to bear againstthe frame-- work es, and to swivel said about said pivot and press theend of the soretv 69 against the framework 68.
